I've been doing a lot of research on All-in-one's running Windows. Not much in terms of quality out there. The only two seemingly all around quality units are the thinkcentre x1 and the asus zen aio. The ASUS as of now comes just in a base version, 5400 rpm hdd and 8bg ram. Supposedly early February the more powerful versions will be released. Early reports say that the asus aio has major fan noise, even with just web browsing.

I have my hopes set on the Thinkcentre x1. Looks great and promises pure SSD and that anti-glare tech in the screen. Can't wait. No release date yet announced. I hope this doesn't turn out to be non-USA vaporware.
